Bipedal robots, in general, are a pretty stilted bunch. Their movements are overarticulated, they wobble, they topple, and when faced with an obstacle -- even one as slight as a slope change -- they often can't overcome it. But that may soon change. This week, researchers from the Univeristy of Arizona published a paper in the Journal of Neural Engineering that describes the development of a new type of robot legs that mimic the neuromuscular architecture of human walking.

Scientists in Norway have more good news for coffee drinkers. Researchers have already found evidence that the drink -- or the beans it's brewed from -- can help with weight loss , reduce one's risk of developing Alzheimer's disease or dementia, boost muscle growth , protect against certain types of cancers, and can even reduce one's risk of premature death , among many other benefits . Now comes word that a cuppa joe reduces physical...

Up and down the West Coast, starfish are dying. Casualties of a mysterious disease known as seastar wasting syndrome, they are dying in Alaska, deteriorating in San Diego and disappearing from long stretches  in between. Death from the disease is quick and icky. It begins with a small lesion on a starfish's body that rapidly develops into an infection the animal cannot fight. Over the course of the disease the starfish's legs might drop off, or even separate from the body and start to crawl away, as you can see in the PBS news story below.

Screaming at your teenagers to discipline them can make their behavior worse - even if you otherwise have a warm family relationship, researchers say. The effects were comparable to those in studies that focused on physical punishments, the researchers said. “From that we can infer that these results will last the same way that the effects of physical discipline do,” the lead researcher, Ming-Te Wang, an assistant professor of psychology in education at the University of Pittsburgh, said in a statement.

The dark dust thrown up by human activity in the deserts of the Southwest hastens the melting of Rocky Mountain snow and ultimately reduces the amount of water flowing into the upper Colorado River by about 5%, scientists reported Monday. The lost water amounts to more than 250 billion gallons — enough to supply the Los Angeles region for 18 months, said study leader Thomas H. Painter, a snow hydrologist at the Jet Propulsion Laboratory in La Cañada Flintridge. "That's a lot of water," said Painter, whose study was published online by the Proceedings of the National Academy of Sciences.

Is 2012 the end of the world? If you scan the Internet or believe the marketing campaign behind the movie "2012," scheduled for release in November, you might be forgiven for thinking so. Dozens of books and fake science websites are prophesying the arrival of doomsday that year, by means of a rogue planet colliding with the Earth or some other cataclysmic event. Normally, scientists regard Internet hysteria with nothing more than a raised eyebrow and a shake of the head. But a few scientists have become so concerned at the level of fear they are seeing that they decided not to remain on the sidelines this time.

In August, NASA's Mars Science Laboratory will reach the Red Planet and begin its search for habitats that could have supported life. The next-generation rover, better known by the nickname Curiosity, will pick its way up a mound in the middle of Gale crater and look for evidence that water once flowed on the Martian surface - a condition that is considered a prerequisite for hosting microbial beings. On an expedition to the California desert this month to demonstrate some of the challenges Curiosity will face on Mars, scientists chatted about the upcoming mission.

A group of scientists warned Tuesday that world leaders must act more swiftly to slow greenhouse gas emissions or risk "abrupt, unpredictable and potentially irreversible changes" from climate change. The American Assn. for the Advancement of Science's blunt report contains no new scientific conclusions. But by speaking in plain, accessible terms it seeks to instill greater urgency in leaders and influence everyday Americans. Scientists said many previous assessments have been long and ponderous, and have failed to shift public opinion on global warming.

Regarding "World Views on Global Warming Are Worlds Apart," Oct. 5: I applaud The Times for coverage of the debate over global climate change. In the attempt to portray the scope of the debate and the complexity of the scientific issues involved, however, your story curiously fails to report the broad scientific consensus on the subject. The 1995 report that is fleetingly mentioned was compiled by the world's preeminent climate scientists, and concluded that there is a discernible impact of human activities on climate.

Famed physicist Stephen Hawking set off chatter in the scientific community in late April when he posited the existence of intelligent aliens on his new TV series, "Into the Universe with Stephen Hawking" —adding that it would be best for human beings to avoid contact with them. Hawking speculated that such aliens would likely be nomads, living in ships after sucking their own planet dry of resources, and hopping from one interstellar refueling station to the next. Earth, he said, shouldn't do anything to encourage their visit.
